I think the most sensible time is evening European time, midday/afternoon US time, early morning in Australia. Maybe shoot for 9 pm GMT and the Saturday rather than the Sunday. (Well, maybe Sunday morning in Australia, but all the more reason for it to be the Saturday then)

I do have ideas, but I'm open to others. My basic idea is to have this be me working on my current area of study, which is hand reading, reads and note taking.

What this means is playing just one table. I won't be looking to get into "interesting spots" as they call them, but rather on extracting the maximum information from the table, and hopefully get into one of two situations where I can directly apply this information.

I imagine the session going something like this:
I go the lobby, select a table explaining why I pick this table, find out if I like the seat that is open and if I do sit down.

I determine if I know any of the villains on the table, and if I do have any information on any of them I will begin scouring my resource to build up a profile on them while I'm playing. Additonally, I make a note of every time a player completes the SB, limps, limp-calls, limp-folds and cold calls. Attempt to steal is also important, but that's tracked automatically. Every showdown I witness I go through the hand history and judge based on the actual holdings how people have played on every street and make notes accordingly.

I intend to play pretty nitty so I have time to analyse everything else that's going on and only get involved if it's clearly profitable for me to do so. As the session progresses more and more hands should become playable as the amount of information I have on my opponents increases.

Initialy my game plan is as follows: Play pocket pairs, AK, AQ in most situations. Play any two cards if the situation suggests that it may be profitable to do so.

The situation is defined as a combination of many factors, such as:
Position
The tendencies and stack sizes of players already in the pot and players left to act
Hand strength

Ideally we'll have at least a couple of showdowns between other players where we've been able to estimate and narrow their hand ranges as the hand progressed and we'll be able to predict who has what before the cards are turned over.

Within this scope of activity I'm sure I'll make enough questionable decisions for us to have things to talk about.
